The natural diamond, explained
Move the controls and watch each of the 4Cs change the stone. Then compare natural and lab-grown honestly — and see what a HATO ring is worth years from now.
Same sparkle. Different story.
Both are real carbon crystals with the same hardness and brilliance. The difference is origin — and what that means for rarity and value.
| Natural diamond (HATO) | Lab-grown diamond | |
|---|---|---|
| Origin | Formed in the earth over billions of years | Grown in a factory in weeks |
| Look & hardness | Identical to the eye · 10 on the Mohs scale | Identical to the eye · 10 on the Mohs scale |
| Rarity | Finite supply — every stone unique | Produced to order, in any quantity |
| Certification | GIA, IGI or SGL certificate states natural | Certificate states laboratory-grown |
| Value over time | 70% lifetime buyback · 80% diamond credit on exchange at HATO | Typically little or no resale value |
| Meaning | A piece of the earth’s history, made heirloom | A modern material choice |
What your ring is worth, later
Estimate your lifetime exchange credit and buyback value under HATO’s published policy. Adjust the split between gold and diamond value on your invoice.
Estimate only, at today’s values. Exchange uses current market value of gold and diamond on the approval date, excludes making charges and taxes, is capped at ₹3,00,000 and is issued as a credit note valid 30 days. Buyback needs the invoice, certificate and a quality check; custom orders are excluded.

IGI
The International Gemological Institute — one of the most widely used labs for certified diamond jewellery.
SGL
Solitaire Gemological Laboratories — an Indian laboratory grading diamonds and jewellery.
